My guess is that the CRC circuitry has fmax1

Your system will have fmax2

If your fmax2 is bigger than fmax1, using crc will degrade your system to fmax1

If your fmax2 is smaller than fmax1, using CRC will not degrade your system performance, you will still only get fmax2.

This is MY personal interpretation.
